CVE-2024-25209
📋 TL;DR
Barangay Population Monitoring System 1.0 contains a SQL injection vulnerability in the delete-resident.php endpoint that allows attackers to execute arbitrary SQL commands via the resident parameter. This affects all deployments of version 1.0 of this software. Attackers can potentially delete, modify, or extract sensitive population data.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise allowing data destruction, data exfiltration, and potential system takeover via SQL injection to RCE if database configuration permits.
Likely Case
Unauthorized deletion or modification of resident records, exposure of sensitive personal information, and potential authentication bypass.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only affecting non-critical data tables.
🎯 Exploit Status
Public proof-of-concept available on GitHub. Simple SQL injection requiring minimal technical skill to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Implement workarounds or migrate to alternative software.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify delete-resident.php to use prepared statements and validate resident parameter
Replace vulnerable code with: $stmt = $conn->prepare('DELETE FROM residents WHERE id = ?'); $stmt->bind_param('i', $_POST['resident']); $stmt->execute();
Web Application Firewall (WAF)
allDeploy WAF with SQL injection rules to block malicious requests
ModSecurity rule: SecRule ARGS:resident "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Isolate system on internal network with strict firewall rules limiting access
- Implement database user with minimal permissions (DELETE only on specific table)
🔍 How to Verify
Check if Vulnerable:
Test /endpoint/delete-resident.php with SQL injection payload: resident=1' OR '1'='1Check Version:
Check application files for version information or readme.txtVerify Fix Applied:
Attempt SQL injection payloads and verify they are rejected or properly handled📡 Detection & Monitoring
Log Indicators:
- Unusual DELETE queries in database logs
- Multiple failed delete attempts with SQL syntax in web logs
- Requests to delete-resident.php with SQL keywords in parameters
Network Indicators:
- HTTP POST requests to delete-resident.php containing SQL injection patterns
- Unusual traffic patterns to the vulnerable endpoint
SIEM Query:
source="web_logs" AND uri="/endpoint/delete-resident.php" AND (param="resident" AND value MATCHES "(?i)(union|select|insert|delete|update|drop|--|#|'|\")")
